VAGINAL SYRINGE.

To all whom t may concern Be it known that l, ANTON C. Eoonns, a citizenof the United States of America, residing in New York, in the borough ofBrooklyn, county of Kings, and State of New York, have invented certainnew and useful Improvements in Vaginal Syringes, of which the followingis a specification.

This invention relates to certain improvements in vaginal syringes inwhich the spout is reversible so as to be capable o-f being stored ininverted position in the interior cavity of the bulb or screwed into theneck of the bulb when the syringe is desired for use; and for thispurpose the invention consists of a vaginal syringe which comprises asoft-rubber bulb having an interiorlythreaded neck, a reversible spoutprovided with a shoulder and screw-threaded portions adjacent to saidshoulder at each side thereof, and a soft-rubber washer or shield thatis applied to the spout into a recess adjacent to the shoulder andprovided with a flaring portion for shedding the liquid, the innercircumference of the washer or shield serving for tightly closing theneck of the bulb, and an interiorly-threaded cap adapted to be screwedover the butt-end of the spout when the same is inserted into the bulb.

In the accompanying drawing, Figure 1 represents a side-elevation of myimproved vaginal syringe, showing the spout inserted into the bulb, Fig.2 is a vertical central section of the same, Fig. 8 is a verticalcentral section, showing the spout in outwardly-extended position foruse, and Figs. t and 5 are respectively a plan-view and a verticalcentral section of the washer or shield used in connection with thespout for shedding the liquid.

Similar letters ofk reference indicate corresponding parts throughoutthe different figures of the drawing.

Referring to the drawing, a represents the elastic bulb of my improvedvaginal syringe, which bulb is made of soft rubber and provided with aflattened bottom al so as to be placed in upright position, and with aninteriorly screw-threaded neck of hard rubber or other suitable materialinserted into the contracted neck ax of the bulb. Into thescrew-threaded neck e2 is inserted the screwthreaded butt-end 1 of thespout b. rIhe length of the spout is somewhat less than the interiordepth of the bulb, so that it can be inserted and stored away ininverted Specification of Letters Patent.

reversed position in the bulb when the syringe is not required for use.For this purpose the butt-end of the spout is provided with a shoulderZ22 and adjacent to the shoul- 6g d er, at the side opposite to thethreaded portion b1, with a second screw-thread b The butt-end of thespout is provided, adjacent to the shoulder b2, with an annular grooved1 into which is inserted a soft-rubber washer or shield CZ, whichserves for shedding the water when the syringe is in use and whichserves also when the spout is screwed into inverted position into thebulb, for producing the tight closure of the bulb at the neck, vas shownin Fig. 2, and prevent the liquid carried in the bulb from leaking outat the neck. The washer or shield d is preferably made of an innerannular portion which iits into the groove of the spout, and with aflaring po'rtion cl2, as shown clearly in Figs. l and 5. Thedelivery-end of the spout is provided with a detachable screw-cap ornipple Z3 which screws on to the deliveryend of the spout, said nipplebeing provided in the well-known manner with an annular opening Zt and adisk Z5 forming a tip by which the medicinal liquid that is to be injected into the vagina by the compression of the bulb is emitted. A cap dis screwed over the outermost threaded butt-end of the spout when thesame is inserted and stored away in the bulb after use. This cap d hasto be removed when the syringe is to be used,

so as to permit the screwing in of the vinner screw-thread b1 of thebutt-end of the spout into the threaded neck of the bulb, as shown inFig. 2.

My improved syringe is of simple construction and can be readilyconverted from a liquid-containing closed bulb into a syringe byunscrewing the spout, reversing it so as to bring it in extendedposition in line with the center of the bulb and rescrewing its butt-endinto the neck of the bulb, in 100 which position of the spout thesyringe is ready for use. After use the spout is unscrewed and insertedin reversed position into the bulb, being screwed tightly on the neck ofthe same, the intermediate washer or shield serving for forming a tightclosure for the liquid contained in the bulb, while it forms a means forshedding the liquid clear of the bulb when the syringe is in use.

The syringe can be easily taken along when traveling and be used withthe liquid placed therein whenever required.

l claiin:

l. A vaginal syringe, comprising an elastic bulb having a screw-threadedneck, a spout screwed in the neck of the same and provided with anannular shoulder, an annular groove adjacent to said shoulder, andscreiv-tl1readed portions adjacent to said shoulder and groove, and aWater-shedding shield oi' sott rubber fitted into said groove.

:2. A vaginal syringe, comprising an elastic bulb provided With aninteriorly-tlireaded neck and an exterior shoulder, a reversible spoutprovided at its butt-end With a shoulder, an annular groove adjacent tosaid shoulder, and a screw-threaded portion adjacent to the shoulder andgroove respectively, and a Water-shedding shield inserted into thegroove, the threaded portions of the spout permitting the screwing ofthe spout in extended position into the neck oli' the bulb or ininverted position into tbe bulb.

3. A vaginal syringe, comprising an clase tic bulb having ascrew-threaded neck, a spout screwed in the neck of the same andprovided with an annular shoulder, an annular groove adjacent to saidshoulder, and screw-threaded portions adjacent to said shoulder andgroove, a Water-sliedding shield of soft rubber fitted into said groove,and an interiorly-tbreaded cap screwed over the outermost threadedbutt-end of tlie spout.

In testimony, that l claim tlie foregoing as my invention, I llavesigned in v name in presence of tivo subscribing Witnesses.
